The document discusses the use and analysis of analogical reasoning. It explains that an argument from analogy compares two things based on similarities to assert that a characteristic true of one thing is also true of the other. Analogies are commonly used in law, where previous cases set precedents that lawyers and judges use to reason about new cases. The document provides guidance on analyzing analogies, including identifying similarities and differences, and assessing whether an analogy is strong or weak based on the relative weight of the similarities versus differences. It also discusses how hypothetical scenarios are used in legal training to prepare students for analogical reasoning in applying laws and precedents to new cases.
